Title: Production of fiber reinforced metallic material
Inventor: BAN KEISUKE
IPC: C22C47/08
Filed: 1984-10-08
Abstract: PURPOSE:To develop a fiber reinforced metallic material which is highly resistant to wear and high-temp. crack and expands less thermally by superposing a large- diameter inorg. fiber layer and small-diameter inorg. fiber layer on the surface of an air permeable mold and molding the same then penetrating a molten metal therein under the pressure. CONSTITUTION:The outside surface of the cylindrical air permeable mold 1 made of a metallic wire or resin wire is placed in a reduced pressure atmosphere. The slurry prepd. by adding large-diameter inorg. fibers of alumina, etc. having 2-20mum diameter into an aq. starch soln. of 10% pulverous powder silica 10 under stirring is introduced to the inside surface of the mold 1. The moisture in the slurry is filtered to the outside of the air permeable mold under the reduced pressure on the outside surface and the alumina fiber layer 2 is formed. The small-diameter fiber layer 3 of silicon carbide, etc. having 0.1-2mum diameter is then formed by the similar method onto said layer and is heated to remove the remaining moisture. The layers are then dried. Such molding is cut to a specified size and is set in a metallic mold. The melt of an Al alloy, etc. is forcibly fed into the metallic mold and is penetrated into two layers of the fiber layers 2, 3 and thereafter the molten metal is cooled to solidify.

Title: Ball tap
Inventor: KOIDE MIDORI
IPC: F16K31/26
Filed: 1982-11-29
Abstract: PURPOSE:To stop the water in a short time and keep the water level at the stop of water constant by a structure wherein a bent sliding surface is formed on a cam connected to a float. CONSTITUTION:When water is charged from a feed water port 19, the water level 15 in a tank is raised with the water flowing out of a discharge port 12 and simultaneously the float 9 is raised. As a result, the cam 3 is pivoted so that the bent sliding surface 4 of the cam 3 presses a roller 10, resulting in tightly pressing a packing 11 against the feed water port 13 by means of a presser 2 in order to stop the water. Three points or the bent point 5' of the cam 3, a shaft 7 and a roller shaft 14 form the fulcrums of a toggle. Therefore, when the bent point 5' presses the roller 10 by the floating-up of the float 9, for a while, during which the angle 5', 7, 14 is large, the float 9 stops its floating-up motion and after a while, when the float 9 gains in appropriate bouyancy, the float 9 pivots the cam 3. The nearer the bent point 5' approaches the straight line that connects the shafts 7 and 14, the larger the force to press the presser 2 about the shaft 7 as a fulcrum becomes. However, when a curved surface 4 and the roller 10 abut against each other, the curved surface 4 is in the state to support the packing 11 with a slight force.

Title: Instrument for detecting molten steel surface
Inventor: IDEUE KAZUO
IPC: B22D11/06
Filed: 1990-08-10
Abstract: PURPOSE:To detect molten steel surface level with good accuracy by correcting error of the molten steel surface level caused by variation of gap between a detecting coil and a belt. CONSTITUTION:At the time of continuously casting, variation of voltage caused by variation of a reactance component (variation of the molten steel surface level) is detected with a first detecting means 12 and the variation of voltage caused by variation of a resistance component (the variation of gap) is detected with a second detecting means 13. Then, output signal of the first detecting means 12 is the signal for the variation of the molten steel surface level, when the gap is varied caused by developing deformation of the belt by the molten steel. Further, the correcting molten steel surface arithmetic means 14 inputs the outputs of the first detecting means 12 and the second detecting means 13 and executes calculation correcting the output of the first detecting means with the output of the second detecting means to output the molten steel surface level corrected with the gap variation. By this method, the variation of molten steel surface level caused by the variation of gap in the continuous casting, is easily corrected and the molten steel surface level can be detected with high accuracy.

Title: Multijunction solar cell
Inventor: KURITA HIROSHI
IPC: H01L31/04
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To provide a structure for a tandem cell type solar cell whose spectral sensitivity characteristic is improved, whose conversion efficiency is high. SOLUTION: In a tandem cell-type solar cell, a top cell 1 which is composed of Inx Ga1-x P and a bottom cell which is composed of GaAs are connected in series by an Iny Ga1-y P tunnel junction layer 33. In the tandem cell-type solar cell, a composition (x) and a composition (y) are selected in such a way that the lattice constant of Iny Ga1-y P constituting the tunnel junction later is made smaller than the lattice constant of Inx Ga1-x P on both sides sandwiching the tunnel junction layer so as to percent Zn as impurities in the tunnel junction layer from creeping out. Then, a desired impurity profile is achieved even after a high-temperature heating process, and a good tunnel junction characteristic is obtained. When the Iny Ga1-y P tunnel junction layer is used, the spectral sensitivity characteristic of a multijunction solar cell is improved.

Title: Controller for improvement of power factor of single-phase inductive load
Inventor: NAKAMURA KYUZABURO
IPC: H02J3/18
Filed: 1985-09-24
Abstract: PURPOSE:To attain the improvement to a power factor of high efficiency for the load by integrating the multiplication values of the current and the voltage by a pi/2 phase shift (given to either one of these current and the voltage) to decide the delayed and advanced power factors and controlling the make and the break of the load to a capacitor via a counter. CONSTITUTION:The load voltage or the load current underwent a pi/2 phase shift via a phase shift circuit 1 and the load current and the load voltage underwent no phase shift via the circuit 1 are processed by a multiplication circuit 2 and an integration circuit 3 respectively. No advance nor delay of a power factor are discriminated and determined when the integration output level of the circuit 3 is equal to zero. Then the advance and the delay of the power factor are discriminated and determined with the positive and negative polarities respectively. Then a counter circuit 6 performs the up- and down-counting actions of timing pulses via a make command discriminating circuit 4 and a break command discriminating circuit 5. A make bank designating circuit 8 controls the connection and cut-off of capacitors C1-C6 to the load. Thus the power factor is improved with high efficiency even with a comparatively small change of the power factor owing to the control carried out based on said delayed and advanced power factors.

Title: Method for suppressing and controlling output when lsi is tested
Inventor: NOGAMI YOJI
IPC: H01L27/04
Filed: 1993-08-25
Abstract: PURPOSE:To alleviate the load for presetting suppression control signals by forming a plurality of output suppression control signals in the inside of an LSI in correspondence with the timing of a strobe point for detecting the output of the LSI, controlling the gate of the LSI, and limiting the number of output buffers, which becomes the output state at the same time as the test time. CONSTITUTION:Based on a pulse signal S1, which is inputted into a clock generating circuit part 16, output suppression control signals A, B and C are formed with delay circuits 17a-17c, an OR circuit 18 and an AND circuit 19. The signals A, B and C enter into AND circuits 5-7 respectively and suppress output buffer circuits 8-10. The suppressions with the signals C, B and A are sequentially released at the timing at strobe points P1-P3. The circuits 10, 9 and 8 are sequentially made to be the output states based on the signal from a system circuit part 1. At a point P4, all the suppressions are released, and the output can be observed. At points P5-P7, the suppressions are sequentially applied, and the suppressed state of all outputs is obtained. Thus, the output suppression as in the conventional method can be performed.
